The need to have a complete control of the length of the carbon nanotubes is one of the most limiting factor in
using nanotubes based devices. In fact their treatments often lead to have different length distribution involving
therefore different properties. In this work we aim at controlling the length of the nanotubes adjusting the
oxidation temperature. Temperature dependence of SWNTs oxidation was analyzed by Raman spectroscopy.
AFM images shows the height of micropatterned self-assembled monolayers of carboxylated SWNTs. SWNTs
forest with different height could be fabricated controlling oxidation temperature in the range of 303K-313K.
